Deep groove ball bearings, formerly known as single-row centripetal ball bearings, are the most widely used rolling bearings. It is characterized by small friction resistance, fast speed, can be used to bear radial load or radial and axial simultaneous action on the mechanical co...……

Tapered roller bearings belong to separate bearings. The inner and outer rings of bearings have tapered raceways. This kind of bearing can be divided into single row, double row and four row tapered roller bearing according to the number of roller rows installed.……

Bearings in the use of the process need to carry out irregular maintenance and maintenance, even so also can not avoid the use of bearings, there will be some failures, we better repair the use of bearings, a detailed analysis of the self-aligning roller bearings in the failure, ...……

The types of needle roller bearings are roughly stamped outer ring needle roller bearings, solid ring needle roller bearings, combined needle roller bearings, thrust needle roller bearings.……

Vibration Signal Analysis and Diagnosis Method of Spherical Roller Bearings By analyzing the vibration signal of rolling bearing with the frequency spectrum, the hidden trouble can be found in time and the fault reason of rolling bearing can be accurately diagnosed.……

Cold extrusion is a kind of forming process in which plastic deformation of metal material is used to obtain the desired shape, size and mechanical properties of parts.Reasonable blank diameter size can ensure the balance of two extrusion deformation degree, in order to reduce th...……

Cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bear radial load. The friction between the rolling body and the ring edge is small, which is suitable for high speed rotation. According to the ring with or without flange, it can be divided i...……

Friction vibration mainly refers to the abnormal vibration of rolling bearings. Generally speaking, friction vibration is easy to occur on large ball bearings, and it is more likely to occur when oil lubrication is used, especially when oil lubrication performance is not good.……

Bearing clearance refers to the total distance that a set of bearing rings can move in a certain direction relative to another set of bearing rings before the bearing is installed with the shaft or bearing box.According to the movement direction, it can be divided into radial cle...……
